ethanknott Posted March 10, 2018 Share Posted March 10, 2018 What kind of epoxy do you guys use for your handles and other bits? I've tried the loctite 5 minute stuff from Home Depot, worked fine but set up too fast for my liking. Got a 20 minute epoxy, 2:1 mix, from System Three. It could totally be from my inability to measure simple ratios, but I've been having issues with the epoxy letting go of the wood and/or metal. I clean and rough up all surfaces before glue up. I don't put any holes in the tang except for the pin holes, which may make a difference. Normally I use a liner of black construction paper/felt stuff from the hobby store to fill in any uneven bits between metal and handle material, also makes it look good. So basically, not sure if it's me being an inferior epoxy-er, or if I'm using an inferior epoxy. Link to comment Share on other sites More sharing options...
Joël Mercier Posted March 10, 2018 Share Posted March 10, 2018 West System's G/Flex and Brownell's AcraGlass seems to be the most trusted. I use G/Flex. 1 Link to comment Share on other sites More sharing options...
Mason Simonet Posted March 10, 2018 Share Posted March 10, 2018 (edited) I use JB weld. On my first couple of knives I used the 5 minute stuff, and the handles are falling off of all of those knives. I haven’t had a problem since I switched. Edited March 10, 2018 by Mason Simonet Link to comment Share on other sites More sharing options...

Zeb Camper Posted March 10, 2018 Share Posted March 10, 2018 +1 Gflex. I had to rehandle a blade not too long ago (customer didn't like the feel). It was a sandwich construction of G10 on a full hidden tang. It was a real challenge! I tried beating it with a hammer, burning it, prying it. I finally opened up a big enough crack to pry it off. Gflex is no joke. Link to comment Share on other sites More sharing options...
Doug Lester Posted March 10, 2018 Share Posted March 10, 2018 AcraGlass or West Gflex. Either one will do fine. I've never had good luck with anything from the hardware stores.

Al Massey Posted March 10, 2018 Share Posted March 10, 2018 I really like G2 epoxy from Lee Valley. Works great on exotic hardwoods. Link to comment Share on other sites More sharing options...
Alex Middleton Posted March 10, 2018 Share Posted March 10, 2018 Maybe I'm just running on borrowed time, but ive actually had really god luck with hardware store 5 min epoxy. I put a stone bit in my Dremel and cut swirly grooves on both sides of my tang and on both handle scales and then make sure everything is clean and dry before glue up.

Thomas Kadatz Posted March 10, 2018 Share Posted March 10, 2018 Here is a good long thread about epoxy. Two guys researched and recorded how different epoxies preformed and made a spreadsheet telling what epoxy is best for what materials and how they all preformed.

I think I'll pin this so it wil be easy to find. Maybe move it to Fit and Finish as well. I've used many things, and as soon as I run out of the bottles of T-88 I have I will go to G-flex. Accraglas is indestructible, and I will continue using it for things like antler stick tangs. It is kind of a pain to work with, though. Link to comment Share on other sites More sharing options...
Joshua States Posted March 12, 2018 Share Posted March 12, 2018 I have used (and continue to do so) a variety of epoxies. What ever you use, keep the mixing pallet and stir stick on the bench while the epoxy sets. Come back after the amount of time that the product instructions tell you it needs to set up and check the pallet and stick. If the leftovers on the mixing pallet aren't set up, you either missed the mixture or are using defective material. Take the handle apart, clean it up and start again. “So I'm lightin' out for the territory, ahead of the scared and the weak and the mean spirited, because Aunt Sally is fixin’ to adopt me and civilize me, and I can't stand it. I've been there before.” The only bad experience is the one from which you learn nothing.

Gary Mulkey Posted March 13, 2018 Share Posted March 13, 2018 I continue to use AcraGlas for two main reasons. One is that it has four times the resin in the mixed condition which gives it extra toughness. Two is that it doesn't degrade like most epoxies. Most will last no more that 8-10 years (or less) before degrading where AcraGlas is good for 100 years. Gary ABS,CKCA,ABKA,KGA Link to comment Share on other sites More sharing options...
Clifford Brewer Posted March 13, 2018 Share Posted March 13, 2018 I've been using Gorilla epoxy for a few years now and had no issues with it ....... I also check the mix leftovers in the set time.

Alan Longmire Posted March 31, 2018 Share Posted March 31, 2018 If you read that Glue Wars thread, they tested for that. The general consensus is that Accraglas can handle it, but you really need pins or Corby bolts or cutler's rivets for a secure mechanical grip as well. 2 1 Link to comment Share on other sites More sharing options...

Well you'd better make her some with synthetic handle materials like micarta because any natural handle material will fail in the dishwasher. OK. So here's my secret epoxy for super duper performance under any circumstances. I can only tell you if you promise not to tell anyone else....... Simpson SET construction adhesive. This is a structural epoxy meant for anchoring steel bolts into concrete. Thick as pig snot. Sets in 7 minutes so work fast. It's a really ugly grey color, so don't get it on anything that is visible (including your fingers). Not for the faint of heart. 1 “So I'm lightin' out for the territory, ahead of the scared and the weak and the mean spirited, because Aunt Sally is fixin’ to adopt me and civilize me, and I can't stand it.
